Hi,
I'm getting the following error trying to send a message using the
shoal example explained on
http://blogs.oracle.com/shreedhar/resource/SimpleGMSSample.java . This
error occurs only when I use a ipv6 only interface.

As we can see, the receive another kind of notifications of each other
(e.g. JOINED_AND_READY_EVENT), however, when I try to send a message
with the sendMessage method of the GroupHandle object, I got the
exception.
I've run the com.sun.enterprise.mgmt.transport.NetworkUtility in order
to take some information about the used network interfaces:

===========================
As we can see, the interface eth1 has been selected to be used although
it supports only ipv6.
So, I have a couple of question here: There is some problem with this
configuration? If there is really a problem with interfaces using IPV6
only, can I workaround this problem using the BIND_INTERFACE_ADDRESS
configuration key? Actually, I think It should be nice bind with a
interface name instead of an address (like, for example "eth0", since
it has IPV4 support) since I have to do the bind over 100 different
machines with different addresses. However, I've tried it with no
success :(
Thanks for your time!
